The United States on Friday demanded that the Syrian government and its Russian allies stop air strikes in northwestern Syria, saying they had a pattern of attacking civilians. An AFP correspondent on Wednesday saw a rescue worker carry the limp body of a tiny girl, her throat covered in blood, in the village of Al-Sahaara in the jihadist-run enclave of Idlib. The US State Department said that attacks in the northwestern area over the previous two days had struck a school and a maternity hospital, killing 12 people.
